APPLICATION GUIDE

Waterborne Polyurethane Resin for Footwear & Shoe Materials

Material selection for footwear-upper and related coating applications where flexibility, cold resistance, surface durability and hand feel can be key requirements.

Material-selection priorities

Final formulation and model selection depends on substrate, coating structure, process conditions and end-use testing. The priorities below are intended for technical scoping, not as a substitute for customer validation.

  • Flex resistance
  • Cold resistance
  • Abrasion / scratch resistance
  • Film clarity and extensibility
  • Hand feel and finish

FOOTWEAR STARTING POINTS

Separate base-layer, coating and bonding requirements

Footwear projects can require very different materials depending on whether the job is a foamed base, a durable coating surface or a lamination/bonding step.

BASE

RU-5503 foaming resin

Aromatic waterborne PU foaming resin with current catalog positioning for waterborne shoe-leather dry-process base layers, soft hand and fullness.
